Lubricating jack and drive shaft bearings

[Bob Miller]

I'm looking for feedback on lubricating these bearings
Do you drill a small hole in the side of them and then use that syringe needle that attaches to the grease gun?
Thanks

DO NOT DRILL ANY HOLES!!! It is stupid simple, Grasp the grease needle in one hand, carefully insert the needle through the rubber seal between the seal and the inner race. When you get it at the correct angle it will go into the bearing 1/4" or so. Now push the grease gun onto the needle zerk, slowly pump 1-2 pumps if you have done this correctly you will see grease push out of the seal slightly at various point around the bearing. Pull out needle and your done. This should not take more than 30sec. I do this every 1000-1500 miles.

DaveRX1 what kind of grease are you using on the bearings the standard lithium grease used on the spindles etc. or wheel bearing grease?

Thanks

For years I have been using "boat trailer" water resistant wheel bearing grease on everything I own from ballbearings to balljoints. No failures.

Thanks Dave That's good to know 8)

Grease

Get yourself some Amsoil water resistent grease. The best for all snowmobile use. Slim

How about Synthetic Grease?

You mean there is a grease that is water soluble?? I have yet to see a grease that is affected by water. Is that what the manufacturers recommend? I'll look in my owners manual.

It would be or should be a wheelbearing compatable grease. It would be fine to use synthetic grease. Yooper is right, what grease is water soluble.

 

[Mighty]

amsoil is synthetic.

One of my biggest peaves is with NTN bearings, with the blue seals.
These are supposed to be premium sled bearings, but the grease cakes up and won't last at all. If I'm forced to use them, I pop the seals off, wash them out, and repack with a wheel bearing grease.

Obviously much easier to just buy another brand, but you almost have to go to a bearing supply shop to find another brand, at least in Canada.

Great marketing job by NTN, I guess, but I wish their bearings came somewhere close to their hype.

If you use their aftermarket drive axle bearing, it's an annual replacement, guaranteed.

Always wondered why Yamaha couldn't design them like Polaris, easy to lube.

Hey stinx,
I got mine at NAPA

Couldn't you install a grease fitting on the driveshaft, and with some ingenuity, on the jackshaft? You'd have to remove the seal, of course.
